K3AsS4
ceramic· JVASP-20924· K3AsS4
K3AsS4 is an inorganic ceramic compound containing potassium, arsenic, and sulfur. This is a specialized research material rather than a production commodity, belonging to the family of mixed-anion chalcogenides that are studied for optical, electronic, and solid-state chemistry applications. The compound is of primary interest to materials researchers investigating novel crystal structures, ion-conducting ceramics, and potentially photonic or thermoelectric properties in sulfide-based systems.

Regulatory Screening
Environmental
RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
